Class
    Foam::uniformFixedValuePointPatchField

Description
    Enables the specification of a uniform fixed value boundary condition.

    Example of the boundary condition specification:
    \verbatim
    inlet
    {
        type            uniformFixedValue;
        uniformValue    constant 0.2;
    }
    \endverbatim

    The uniformValue entry is a Function1 type, able to describe time
    varying functions.  The example above gives the usage for supplying a
    constant value.
